Beyond Special and General Relativity. Neutrinos and Cosmology

TL;DR

This paper explores the idea that cosmic acceleration and neutrino oscillations might be indicators of new physics at low energies, challenging the conventional cosmological constant and neutrino mass explanations.

Contribution

It proposes a phenomenological approach suggesting that these phenomena could reveal new physics beyond current models.

Findings

Cosmic acceleration and neutrino oscillations may be signs of new low-energy physics.

Current explanations using cosmological constant and neutrino masses are conceptually unsatisfactory.

Alternative phenomenological models could better account for these phenomena.

Abstract

The widely accepted description of the present cosmic acceleration and the neutrino oscillations in terms of a cosmological constant and neutrino masses, respectively, seems conceptually not very satisfactory. From a phenomenological perspective, the possibility that those phenomena are instead the first windows to new physics at very low energies is explored.
